Method and apparatus of preparing catalyst for fuel cell

Abstract

A method for producing a catalyst for a fuel cell comprising: a) injecting carbon particles into a fluidized bed reactor; b) evacuating the fluidized bed reactor to form a base pressure; c) introducing a catalytic metal precursor together with a carrier gas into the fluidized bed reactor to contact the catalytic metal precursor with the carbon particles; d d) purging a purge gas into the fluidized bed reactor; e) introducing a reaction gas into the fluidized bed reactor to attach the catalytic metal precursor to the carbon particles; and f) purging a purge gas into the fluidized bed reactor, wherein, the catalytic metal is attached to the carbon particles in a form of nano-sized spot.

Description

TECHNICAL FIELD[0001]The present disclosure relates to a catalyst production method and a production apparatus for a fuel cell. More specifically, the present disclosure relates to a method and apparatus for producing a catalyst for a fuel cell using a fluidized bed reactor.PRIOR ART[0002]In addition to the electrode material of the fuel cell, the catalyst is also continuously improving performance, and the proposed catalyst includes carbon black as a support and platinum spots are incorporated therein. Platinum is a very expensive metal and uses as little as possible but maximizes the surface area. Therefore, it is desirable to have a form where the platinum spot is small, uniform and active even with the same amount of platinum. Conventionally, such a catalyst is manufactured by a wet process as an example.[0003]In conventional wet processes, the mass production process takes almost a week. In addition, due to the use of chemicals, manufacturing costs are high due to environmental...

AI Technical Summary

Benefits of technology

[0046]By using a fluidized bed reactor, a catalyst metal spot having a small and uniform size; and distribution; is formed on the carbon particles, thereby producing a fuel cell catalyst having a large surface area of the catalyst metal.

Problems solved by technology

Platinum is a very expensive metal and uses as little as possible but maximizes the surface area.

In conventional wet processes, the mass production process takes almost a week.

In addition, due to the use of chemicals, manufacturing costs are high due to environmental problems, post-treatment, and stabilizer input due to the disposal of chemicals.

At this time, large sized platinum spots are undesirable because they counteract the expansion
